Lions quarterback Matthew Stafford has "looked precise" and comfortable over the first two days of minicamp, says the Detroit News. The coaching staff has done a lot to help with his footwork, a problem for him over the past couple of seasons. As he's learning the details of a new playbook, Stafford will be allowed to change plays at the line of scrimmage. The idea behind it is if he sees a coverage that could make a route change to one of his receivers more favorable, he can take advantage. 

"He's done it before, he has a good understanding of it, and he even does some now," coach Jim Caldwell said. "That's kind of part of the package because he's got to have a little bit of autonomy from time to time to get you in the right play. You may be able to call a play, but he's out there on the field. He can see it happening. He can see the defense, so there's some times we have some overriding checks and things of that nature that we'll utilize."
